Overview:
The BlackJack 13040 is a 4in blast gate with two distinct connection types — one on each side. The hose-side port features a threaded connection sized to accept BlackJack's flexible dust collection hose directly, eliminating the need for a hose clamp and the risk of the hose working loose over time. The other end uses a standard 4in tapered male fitting that seats into 4in tapered female fittings and also fits directly into standard 4in metal furnace duct.
Features:
- Threaded hose-side connection locks BlackJack flexible dust collection hose securely in place — no hose clamp required
- Opposite end uses standard 4in tapered male connection compatible with 4in tapered female fittings and 4in metal furnace duct
- Dual-connection design suits a wide range of shop dust collection system configurations
